In October 2019, Sven Taylor published a sobering article titled Is Tor Trustworthy and Safe?. In it he argues that (numbering mine),
- US government agencies can de-anonymize Tor users on a “wide scale”
- ...proven by a 2017 case in which the FBI de-anonymized Tor users
- Tor developers are cooperating closely with US government agencies
- Anybody can operate Tor nodes and collect your data and IP address; there's no quality control for nodes
- Malicious Tor nodes do exist
- No warrant necessary to spy on Tor users
- Tor was created and is funded by the US government
- Tor users are targeted merely for using Tor
A few other aspects are highlighted, even though they're mentioned in the documentation (e.g. potential IP address leaks via PDFs). The solution offered by the article is to use Tor through a VPN.
Which of these claims are the most serious problems with Tor, and how can users defend against them?
